M1W w Q Patented Get. 27, 1931 ITED STATES PATENT OFFICE ERNEST KAISER, OF CHICAGO, ILLINOIS, ASSIGNOR TO FRIGID FLUID COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS ASPIRA'IING AND EMBALMING- DEVICE) Application filed January 18, 1930. Serial No. 421,788.

The invention relates to aspirating and embalming devices and has among its principal objects the provision of a construction which is relatively small, light in weight and compact so that it may be readily transported from one place to another and includes means whereby the device may be set to accomplish either the production of suction or pressure to withdraw and pump fluid from or to a body and includes means whereby the suction and pressure is regulated so that the device may be set to provide the required reduced or increased pressure to compensate for different sized bodies upon which work is being performed and to also provide means whereby the operator may ascertain the degree or amount of pressure applied during the performance of this work- The invention has a further object the provision of a construction in which the several elements are encased and the provision of means whereby certain of the elements may bemanipulated to control the actuation of the device from the outside of the casing, such as for instance, the means for changing over the device from suction to pressure and vice versa, the regulation of the degree of pressure and suction and also the determination of the pressure being produced. so The invention has these and other objects, all of which will be more readily understood when read in conjunction with the accompanying drawings which illustrate one embodiment of which the invention is susceptible, it being obvious that changes and modifications may be resorted to without departing from the spirit of the appended claims forming a part hereof.

Figs. 8 and 9 are sections respectively taken on lines 8 and 9 of Fig. 6.

Whereas the device as herein shown is described as employed for use in the embalming art, it is manifest that the construction is not limited to this use and may be successfully employed by the medical profession to inject or extractvarious fluids to and from the body of a patient.

By referring to Figs. 1 and 2, it will be noted that the various elements employed in the structure are mounted upon a base generally designated 10 and are enclosed within a casing 11 having a handle 12, the casing having extensions or posts such as 13 which are adapted to be passed through apertures 14: in the base and held relatively to thebase through the agency of a holding means such 7 as that generally designated 15 and 16 most clearly shown in Fig. 5. The device contemplates the use of an electric motor 17 having a socket 18 preferably arranged-in amanner so that a plug (not shown) may be associated with the socket through an opening such as 19 provided in the casing.

' The motor 17 is provided to actuate a pump generally designated 20, the pump being provided to. produce either an increased or decreased air pressure to thereby provide the necessary suction or pressure depending upon Whether it is desired to supply or extract fluid to or from a body. The shaft of the motor 17 is provided with a worm 21 which cooperates with a worm wheel 22, the latter of which is secured to one end of a shaft 23 journalled in a bearing 24 secured the medium of a standard 30. It is manifest from the explanation of the structure thus far explained that when the motor is energized, thepump is actuated to create both a reduced and a compressed air condition, and therefore, when proper connections are made between the pump and the body of a person, fluid will either be ejectedor withdrawn therefrom. A valve mechanism generally designated 31 is associated with the pump chamber and provides means for determining and controlling which of these pressures is to be applied and includes means for regulating these pressures, all of which will be explained in the following:

A tubular connection 32 is made with a .pressure regulating chamber 33 and this pressure regulating chamber 33 has an extension 34 whereby a tubular connection such as 35 may be made therewith, it being understood that the tube 34 provides means of communication between the device illustrated in Figs. 1 and 2 and the receptacle designated 36 shown in Fig. 7. The receptacle 36 has a tubular extension 37 which is adapted for separable connection with the tube 35, and in addition, is provided with a goose neck or tubular element 38 to which a tube 39 is attached to form a connection be tween the various elements thus far explained and the body of the person being operated upon.

It is manifest that when the valve mechanism generally designated 31 is arranged to produce a reduced air condition, this reduced air condition will exist in the pressure regulating chamber 33, the extension 34, the tubular element 35 and the. receptacle 36; this being accomplished through the goose neck 37 which will extract air from the receptacle 36 and cause a reduced air pressure to exist in the goose neck 38.

and the tubular extension 39. This reduced air pressure will exhaust fluid from the body, it being understood that the extension 40 of the goose neck 38 extends to adjacent the bottom of the receptacle 36 while the goose neck 37 terminates near the top of the receptacle and therefore, prevents fluid supplied to the receptacle 36 from entering the mechanism carried by the plate 10 and encased within the casing 11.

The pressure regulating chamber 33 is provided with a compound pressure gauge 41 and this pressure gauge is connected with the pressure chamber through the agency of suitable pipe connections including the pipe unions respectively designated 42 and 43,

which latter provide substantially a universal connection between the gauge and the pressure chamber which allows the gauge to bearranged in any one of several positions con venient for observation by"the user of the device. To this end, the casing 11 may have an opening 44 through which the gauge 41 may be passed to respectively arrange the gauge within and without the casing. This opening may be closed when the gauge is in an inoperative position within the casing by means of a closure or tra 45. 7

It will be noted by re erring particularly to Fig. 6 wherein the valve mechanism for controlling the provision of either'a reduced or increased air pressure within a receptacle such as that generally designated 36 is illustrated, that the piston cylinder 29 is connected with a head 46 having a port47 which completes a communication between the cylinder and the head. The head has a passage 48 and a branched passage 49 which respectively communicate with the check valves 50 and 51 and a regulating valve generally designated 52, the latter being employed to regulate the degree of reduced air pressure existing in the tubular passage 35 and other elements connected therewith. The passage 48 is provided with a pressure regulating valve 53 for regulating the degree of increased pressure supplied to the tubular element 36 and its connections. The check valves 50 and 51 are connected through the agency of couplings such as 54 with a cut-off valve generally designated 55 having a stem and a knurled head 56, the stem of which extends through an opening in the casing to thereby locate the knurled head thereof so that it is convenient and accessible for use by the operator.

It may be here stated that the regulating valves 52 and 53 are also each provided with a stem and knurled head respectivel designated 57 and 58 and that these hea s also extend through the casing 11 so that they are accessible for use by the operator. The body of the cut-off valve 55 is provided with an extension 59 which provides means for completing a connection between the pump and valve mechanism and the pressure regulating chamber 33 through the agency of the tube 32. The cut-off valve 55 is provided with a port 60 and a passage 61 and is also provided with the port 62 and passage 63. The

respective ports and passages 60, 61, 62 and Y 63 are designed to complete a communication between the respective passages including the check valves 50 and 51, it being manifest that when the valve 55 is arranged inthemanner shown in Fig. 6, that upon the suction stroke of the piston 28, a reduced air condition is created in the passages 47 and '49, 60 and 61, the check valve 50 allowing the reduced air pressure created, to exist in said passages while the check valve 51 at this time is seated to close the other branch of the passage 49. It is manifest that upon the compression stroke of the piston, the check valve 50 will be seated and the valve 51 unseated, however, since the position of the passages 62 and 63 air under compression is prevented from passing through the extension 58.

It will be noted that each of the regulating valves 52and 53 are provided with ports or passagesrespectively designated 64 and 65 which will allow air under compression during the compression stroke of the piston to escape to atmosphere. The stem 66 of the valve 57 is provided with a valve portion 67 which is designed to cooperate with the valve I seat 68 to. thereby provide means for regulating the degree of reduced air pressure created upon the suction stroke of the piston, it being evident that the distance between the valve 67 and the seat 68 thereof provides for this regulation.

When the control valve 55 is rotated so as to provide a communication between the passage 63 and the port 62, the passage 61 and the port 60 are then arranged to prevent the existence of a reduced air pressure in the extension 58. When the passage 63 and port 62 are arranged in this last mentioned position, it is manifest that upon the compression stroke of the piston, the check valve 51 is unseated which allows the pressure created by the piston to pass said check valve, travel through the port 62 and the passage 63 and into the extension 58, the tubular member 32 and the pressure regulator chamber 33, it being understood that the valve 67 is at this time fully closed. It is evident that manipulation of the head 58 of the-valve will apply a variable tension to the coil spring 69 and'thus hold the valve 70 against the valve seat provided therefor which will vary the degree of tension applied to the valve 70 and thus determine the degree of pressure of the increased air pressure introduced to the pressure chamber 33 and the various elements connected therewith.

By referring to Figs. 8 and 9, it will be noted that the housing for the valve 55 is provided with ports 71 and 72 which will allow the escape of either increased or reduced air pressure therethrough upon the position of the valve 55.

By referring to Fig. 5, a.- means for releasably locking thecover 11 to the base plate 10 is shown in detail. This means, inthe present instance, includes a plurality of reciprocably mounted elements 73 having the finger pieces 74. The 'reciprocable elements 73 are held in distended condition through the agency of a coil spring 75 which maintains the ends such as 76 of the reciprocable elements in engagement with a notch 77 provided adjacent the lower extremities of each of the posts or legs 13 (see Fig. 2).

It is evident that when the finger. pieces 74 are. manipulated to bring them towards each other, the spring 75 is compressed and the ends 76 of the reciprocable elements are released from the notches 77, allowing the depending cover or casing 11 to be disconnected from the base plate 10.

From the foregoing description of the construction, it is manifest that when a proper.

connection is formed with the motor 17, the latter will be actuated which causes the piston of the pump to reciprocate producing a reduced and increased air condition, either one of which is also caused to exist in the tubular element 32 and the various elements connected therewith, the reduced or increased air pressure existing therein being controlled through the agency of the control valve 55. It is further evident that the valves respectively designated 57- and 58 provide a means for varying and regulating the degree of pressure either reduced or increased, existing in the tubular passage 32 and the elements connected with this passage. It is further manifest that the entire structure is of a relatively small, compact,- and light that the pressure existing in the tubular connection such as 35 and the elements connected therewith will be of a constant and regular character and by virtue of the fact that the compound gauge connected with the pressure chamber is capable of substantial universal movement, this element may be located within and arranged on the outside of the casing and may be adjusted for convenient observation by the user.
